[ale] network issue?

[Jerry Yu]

It may help to use wireshark or tcpdump to capture traffic on your
computer. I'd start with DNS and http first.  If the dns server could
not resolve preoperly or consistently, you may see delay due to dns
timeout while no traffic going thru your router. If http request is
sent out right away, u then looking at traceroute and whatnot.
